I open this thread in the hope that someone will help me with this problem. I've been looking for a non-stop solution for two days, I've watched lots of videos and searched everywhere but nothing. Then I found a user on this forum who had a similar problem and fixed it.
The problem is as follows:
After using a regedit file that changed the GPU priorities for a game on the PC, upon rebooting I was met with the recovery screen and Windows telling me it didn't boot properly. I've already tried the most basic things found in tons of online videos, but I haven't solved anything. Windows at every solution used and every reboot continues to show me the "diagnostics in progress" screen and then always goes to the blue recovery screen where the only options are restart or advanced options.
Some solutions I've tried are:
- Windows startup repair, in the advanced options of the recovery screen.
- used a previous restore point: I have two of them but neither of them, despite the success of the operations, manages to start windows correctly.
-sfc/ scannow and chk disk, yielded no results.
- regback it didn't contain registry backups because I have an up-to-date version of windows that no longer creates such backups.
- i tried rebuild cbd, to no avail (if i followed all the steps correctly)
- I tried to uninstall the quality and feature updates, from the blue screen recovery in advanced options, but an error won't let me do it.
- finally, I used ShadowCopiesExplorer (if it's called that) to manually access the shadow copies and replace the sam, security, default, etc... files, from the Windows\system32\config folder of the shadow copy to the same folder currently in use in windows . those files must have contained the old registry files if I'm not mistaken (?). I also kept the old sam, security, sytem, default, etc... (I replaced only 5 files to be precise, the same ones that would be in regback) renaming them OLD at the end.
I'm desperate right now and don't know what else to do. If anyone could help me find a solution I would be immensely grateful. I don't want to have to reset windows even if it keeps my files, because I have tons of apps and customizations I don't want to lose.
Thanks in advance.
- I also tried disabling the graphic drivers on startup, via a 3rd party program, but that didn't work either.
my pc is an HP laptop with integrated and dedicated graphics cards.
note: when turned on the PC, after the HP logo, initially the message "attempting recovery" appears under it, then the screen goes black and appear a very fast pop-up of a window, which closes immediately. I think is a service that fails to start and this probably does not allow windows to start. then another screen starts which leads to the writing "diagnostics in progress" to finally arrive at the fateful blue recovery screen.
